Upper abdominal surgical treatment may have reduced respiratory muscle function and mucociliary clearance, which might be a consequence of postoperative pulmonary complications (PPCs). The threshold inspiratory muscle training (IMT) may serve as an effective modality to improve respiratory muscle strength and endurance in patients. However, whether this training could help patients with upper abdominal surgery remain to be determined.

The initial training intensity of the preoperative threshold IMT trainer (DofinTM, Breathing Strength Builder, Taiwan) was moderate to high intensity (≥50% of MIP), which was according to the patient's baseline level and increased by 5-10% per week. The frequency is 25-30 minutes each time, twice a day and five days per week for at least two weeks. The participants would receive at least 10 times training sessions before surgery
